Arthritis is an ever-growing and painful problem. According to a 2022 study by the Center for Disease Control, 18.9% of adults aged 18 to 65 suffer from some form of arthritis (and even that number might be too low). However, scientists from the University of Utah, New York University, and Stanford University have found an old school way to help those with knee osteoarthritis relieve pain without medication or surgery. Their answer? Walk it off.

Their study found that adjusting the angle of a person’s foot when they’re walking and retraining the gait of a person with osteoarthritic knees provided comparable pain relief to medication. On top of that, the participants who adjusted and retrained the gait show less cartilage deterioration over time compared to other participants given placebo treatments.

In the study, 68 participants with osteoarthritic knee pain had MRIs taken, and were split into two groups—one was given a placebo treatment and the other group was trained to walk differently. Both groups then took part in six weekly lab-based training sessions in which participants in the gait training group had a device attached to their shins that guided them to keep their feet at the desired angle while walking on a treadmill. Following the training, the participants practiced their “prescribed gait” for 20 minutes each day until it turned into a natural habit and did follow-up visits to ensure that they stuck to their new gait. After a year, the participants self-reported their experience of knee pain and had a second MRI to assess their knee cartilage after the study, with both showing promising results.

“We’ve known that for people with osteoarthritis, higher loads in their knee accelerate progression, and that changing the foot angle can reduce knee load, so the idea of a biomechanical intervention is not new, but there have not been randomized, placebo-controlled studies to show that they’re effective,” said study author Dr. Scott Uhlrich to SciTechDaily.

As Ulhrich said, adjusting how you walk to reduce the weight and stress on the knees isn’t a new recommendation from doctors. In fact, it has mostly been recommended to older people experiencing stiffness and pain so severe that it’s hard to move. And while gait retraining is mostly recommended by the Arthritis Foundation, one main issue is that it takes concerted effort and time from both patients and the doctors to ensure that the retrained gait becomes a permanent habit.

That said, this effort is necessary compared to other current pain management options. There is a global concern about osteoarthritic patients becoming addicted to the pain medication they’re prescribed for their ailment, creating a great need for alternative techniques and treatments to reduce pain. However, according to doctors like Ulhrich, this study reveals that this can be a way for younger people to manage their pain and develop a permanent habit that can improve and extend their quality of life until more drastic treatment measures need to be taken.

“Especially for people in their 30s, 40s, or 50s, osteoarthritis could mean decades of pain management before they’re recommended for a joint replacement,” Ulhrich said. “This intervention could help fill that large treatment gap.”

It’s important to note that if you think this method might help manage your arthritic pain, you should consult your doctor before attempting this or any form of treatment. They can help you find the best methods for you and refer you to the proper care professionals equipped to help you the best way possible.

  • It’s a myth that baby boys are less social than girls – a new look at decades of research shows all babies are born to connect

    Girls and boys are equally social at birth.

    This finding, based on my team’s synthesis of six decades of research, may come as a surprise. Gender differences in adults’ social sensitivity are famous. Women outperform men at recognizing faces and emotions, and they score modestly higher on measures of empathy. They are likelier to take jobs working with people, such as in teaching and health care, whereas men are likelier to choose jobs working with “things,” such as in engineering or plumbing.

    But how early do these differences emerge, and are they a matter of evolution or social learning? For years, some theorists have argued the former: that the difference is innate, built into the brain hardware of girls and boys through Darwinian selection. But this perspective relies almost exclusively on just one high-profile, yet deeply flawed, study of 102 newborns.

    Mining the neonatal research trove

    Realizing that psychologists have been studying newborns’ social orientation for decades, my team of neurobehavioral researchers and I set out to collect all the data – every published study that has compared boys’ and girls’ attention to social stimuli in the first month of life. Our goal was to better test the hypothesis of an inborn gender difference in attention to, or interest in, other people.

    Our study was a systematic review, meaning we searched through every published report indexed in both medical and psychological databases from the 1960s onward.

    We cast a wide net, looking for any research that measured newborns’ attention to or preference for human faces or voices and that reported the data separately by gender. Importantly, we did not limit our search to the terms “gender difference” or “sex difference,” since these would bias the collection by potentially excluding studies that failed to find boy-girl differences..

    As expected, we unearthed dozens of studies comparing newborn boys and girls on social perception: 40 experiments reported in 31 peer-reviewed studies and involving nearly 2,000 infants. The majority of studies measured the amount of time newborns spent looking at faces, either at a single face or comparing a baby’s preference between two faces of differing social value, such as their own mother versus a woman who was a stranger.

    Our data collection was large enough that we were able to carry out meta-analysis, which is a statistical method for combining the results of many studies. Meta-analysis essentially turns many small studies into a single large one. For studies measuring neonates’ looking time at faces, this included 667 infants, half of them boys and half of them girls.

    Newborn boys and girls are similarly attentive to faces, with the distribution of time they spend looking almost completely overlapping. Data from Karson et al. plotted using tool at sexdifference.org.

    The result was clear: nearly identical social perception between baby boys and girls. There was no significant difference between genders overall, nor was there a difference when we focused only on studies measuring babies’ gaze duration on a single face, or only on studies measuring babies’ gaze preference between two different faces.

    Our search also netted two other types of studies. One focused on a remarkable behavior: newborns’ tendency to start crying when they hear another baby cry. An early study found this “contagious crying” to be marginally more common in girls. But when we performed meta-analysis on data across nine contagious-crying experiments, including 387 infants, there was again no solid evidence for male-female difference.

    The last dataset we analyzed compared babies’ orientation to both social and inanimate objects using a newborn behavior assessment scale developed by legendary pediatrician T. Berry Brazelton. Across four studies involving 619 infants, girls did pay somewhat greater attention to the social stimuli (a human face or voice), but they also paid more attention to the inanimate stimuli (a ball or the sound of a rattle).

    In other words, girls in this test seemed a bit more attuned to every type of stimulus, perhaps due to a general maturity advantage that they hold from fetal development through puberty. But there was nothing special about their interest in people, according to the Brazelton assessment.

    Boys, too, prefer faces

    Our findings align with other well-designed studies, including one finding that 5-month-old boys and girls equally prefer looking at faces over toy cars or other objects, and another finding that 2-month-old boys actually perform better than girls at detecting faces. So taken together, current research dispels a common myth that girls are innately “hardwired” to be more social than boys in early life.

    The truth is that all babies are wired for social engagement at birth. Boys and girls are both primed to pay attention to human faces and voices, which, after all, belong to those who will keep them fed, safe and comforted.

    Despite their best intentions, most parents cannot help but stereotype their infants by gender and begin treating boys and girls differently early on. Presuming that sons are already less social is not a recipe for remedying this bias. Our research can help dispel this myth, giving every child, male or female, the best possible start for connecting with and caring about other people.

  • Licensed therapist shares 6 signs you’re doing a lot better than you think you are
    Photo credit: CanvaA woman in quiet contemplation.

    For many people, it’s easy to overlook progress because it often lacks clear milestones. There can be increased anxiety and stress from feeling like they’re still catching up or even falling farther behind.

    In a recent Instagram post, licensed therapist Jeffrey Meltzer points out six signs that people are doing better than they think. He breaks down a pattern of achievements that tend to be easily missed. How individuals interpret their past, how they presently handle their relationships, and even asking simple questions, reveal a very different story about where they’re at in their lives and where they’re going.

    Surviving the unsurvivable

    Meltzer begins, “You’ve survived everything that once felt unsurvivable. Every hard season, every moment you thought you wouldn’t get through. You did. That is no small feat. Your brain forgets those victories the moment they pass, but they still count.”

    Learning how to cope with life isn’t just about “toughness.” Resilience is a measurable, multi-layered process tied to effective coping strategies. A 2025 study in Psychology Today points out that rising above adversity isn’t the simple solution. Having support systems that function well enough means you don’t have to.

    Becoming what we desperately want

    “You’ve changed in ways you once desperately wanted. Think back to who you were three or five years ago. Some of the growth you desperately wanted back then, you’re living it now.” Meltzer adds, “However, your brain likes to move the goal post without telling you.”

    People constantly face an adjustment to satisfaction because expectations rise over time. A 2024 study in Springer Nature Link explored the hedonic treadmill. Even after massive achievements, the boost of happiness doesn’t last as long as people expect.

    Knowing what we don’t like

    “You know what you don’t want.” Meltzer continues, “That might sound like a consolation prize, but it’s actually hard-earned clarity. A lot of people waste years chasing the wrong things. But knowing what drains you, what doesn’t serve you, what you won’t settle for anymore, that’s actual progress.”

    Psychology emphasizes that self-awareness leads to better behavior and stronger emotional regulation. A 2023 review in the Annual Review of Organizational Psychology and Organizational Behavior found that this process brings a clearer sense of who we are and who we are becoming.

    An easy relationship to navigate

    “You have at least one relationship that feels easy. You’re at least one person that doesn’t require a performance from you. Someone who you can be a little bit of a mess around. You don’t need to be perfect around them, and it feels easy.” Meltzer explains the value, saying, “That kind of connection is rarer than people like to admit.”

    Strong interpersonal relationships are key predictors of mental health and well-being. A 2024 study in the National Library of Medicine found that secure attachment helps people experience fewer of the symptoms associated with anxiety and depression. Even one stable, supportive relationship is linked to long-term well-being.

    Learning something new

    “You’ve learned something in the last year.” Meltzer explains, “Whether it’s a skill, a perspective, a hard lesson, all of it counts. Remember, a brain that’s still learning is a brain that’s still growing.”

    The human brain remains capable of learning and adapting throughout a person’s life. A 2025 study published in MDPI found that brain neuroplasticity allows traits such as emotional regulation and awareness to be reorganized and improved over time.

    Asking better questions

    Lastly, Meltzer offers, “You’re asking the right questions. The fact that you’re reflecting and trying to see your life more clearly, that’s a sign of someone who hasn’t given up.”

    Believing that change is possible shapes emotional recovery and motivation. A 2025 study in Springer Nature Link showed that a growth mindset leads to better psychological outcomes and improves a person’s ability to adapt to new situations.

    People are doing better than they think

    These six signs shared by Meltzer helped viewers understand that they’re doing better than they think. As people flooded the comment section, some seemed to struggle with #4, having that one reliable friend. Still, most were just appreciative.

    “This made me feel so much better”

    “i don’t have number 4 unless my dog counts”

    “all I need now is the 4th one, I’m working towards it by socializing more it’s challenging but I’m learning”

    “I’m winning despite feeling defeated”

    “I needed this right now.”

    “Does Mom count for #4?”

    “I’ll give myself credit, it been rough recently, 5 out of 6 is better than I expected”

    “This made me remember how far I have become even tho I still work on things, it’s so good to get these reminders this genuinely made my day”

    Meltzer tries to help people reframe their perspectives. Often, things look like they’re “not enough” even though the actual evidence suggests otherwise. Psychology reveals growth is incremental and easy to miss. The fact that a person wants to do better is the clearest sign that personal growth is already underway.

  • Reclaiming water from contaminated brine can increase water supply and reduce environmental harm
    Photo credit: Dean Musgrove/MediaNews Group/Los Angeles Daily News via Getty Images The Hyperion Water Reclamation Plant in Los Angeles handles a massive amount of sewage and wastewater.

    The world is looking for more clean water. Intense storms and warmer weather have worsened droughts and reduced the amount of clean water underground and in rivers and lakes on the surface.

    Under pressure to provide water for drinking and irrigation, people around the globe are trying to figure out how to save, conserve and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater.

    But for all the clean water they may produce, those processes, as well as water-intensive industries like mining, manufacturing and energy production, inevitably leave behind a type of liquid called brine: water that contains high concentrations of salt, metals and other contaminants. I’m working on getting the water out of that potential source, too.

    The most recent available assessment of global brine production found that it is 25.2 billion gallons a day, enough to fill nearly 60,000 Olympic-sized swimming pools each day. That’s about one-twelfth of daily household water use in the U.S. However, that brine estimate is from 2019; in the years since, brine production is estimated to have increased due to the continued expansion of desalination plants.

    That’s a lot of water, if it could be cleaned and made usable.

    How is brine disposed?

    Today, most brine produced along the coastline is released into the ocean. Inland cities without this option typically leave brine in ponds to evaporate, blend it with other wastewater, or inject it into deep wells for disposal.

    However, most of these methods require strict environmental protections and monitoring strategies to reduce harm to the environment.

    For instance, the extremely high salt content in brine from desalination plants can kill fish or drive them away, as has happened increasingly since the 1980s off the coast of Bahrain.

    Evaporation ponds require specialized liners to prevent the brine from leaching into the ground and polluting groundwater. And when all the water has evaporated, the remaining solids must be promptly removed to prevent them from blowing away as dust in the wind. This happens in nature, too: As the Great Salt Lake in Utah dries up, salty windblown dust has already contributed to significant air pollution, as recorded by the Utah Division of Air Quality.

    Brine injected into the earth in Oklahoma, including into wells used for hydraulic fracking of oil and natural gas, was one of several factors that led to a 40-fold increase in earthquake activity in the five-year period from 2008 to 2013, as compared to the preceding 31 years. And wastewater has been documented to leak from the underground wells up to the surface as well.

    Emerging treatment technologies

    Researchers like me are increasingly exploring brine’s potential not as waste but as a source of water – and of valuable materials, such as sodium, lithium, magnesium and calcium.

    Currently, the most effective brine reclamation methods use heat and pressure to boil the water out of brine, capturing the water as vapor and leaving the metals and salts behind as solids. But those systems are expensive to build, energy-intensive to run and physically large.

    Other treatment methods come with unique trade-offs. Electrodialysis uses electricity to pull salt and charged particles out of water through special membranes, separating cleaner water from a more concentrated salty stream. This process works best when the water is already relatively clean, because dirt, oils and minerals can quickly clog or damage the membranes, reducing the performance of the equipment.

    Membrane distillation, in contrast, heats water so that only water vapor passes through a water-repelling membrane, leaving salts and other contaminants behind. While effective in principle, this approach can be slow, energy-intensive and expensive, limiting its use at larger scale.

    A look at smaller, decentralized systems

    Smaller systems can be effective, with lower initial costs and quicker start-up processes.

    At the University of Arizona, I am leading the testing of a six-step brine reclamation system known as STREAM – for Separation, Treatment, Recovery via Electrochemistry and Membrane – to continuously reclaim municipal brine, which is salty water left over from sewage treatment.

    The system combines conventional methods such as ultrafiltration, which removes particles and microbes using fine filters, and reverse osmosis, which removes dissolved salts by forcing water through a dense membrane, alongside an electrolytic cell – a method not typically employed in water treatment.

    Our previous study showed that we can recover usable quantities of chemicals such as sodium hydroxide and hydrochloric acid at one-sixth the cost of purchasing them commercially. And our initial calculations indicated the integrated system can reclaim as much as 90% of the water, greatly reducing the volume of what remains to be disposed. The cleaned water in turn is suitable for drinking after final disinfection using ultraviolet or chlorine.

    We are currently building a larger pilot system in Tucson for further study by researchers. We hope to learn if we can use this system to reclaim other sources of brine and study its efficacy in eliminating viruses and bacteria for human consumption.

    We have partnered with other researchers from the University of Nevada Reno, the University of Southern California and the U.S. Army Corps of Engineers to help communities in the Southwest secure reliable water supplies by safely reusing municipal wastewater to serve everyday water use.
